Check Vauxkhall Astra suspension

If you notice a suspension noise when you pass a speed bump on your Vauxkhall Astra, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To examine if this is the problem that worries you, take a dented road and listen to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of swapping them quickly or you may ruin other parts and have to make more important repairs.
